has anyone seen this error when trying to import a pulumi stack?

error: could not deserialize deployment: decrypting secret value: [400] Message authentication failed

Is this exporting a stack from one backend and importing into another? The error message there isn't great - but this scenario isn't yet fully supported due to https://github.com/pulumi/pulumi/issues/3683. Does that issue describe what you are trying to do?

sounds similar. we're doing

pulumi export

to back up state and i'm trying to recover and old state with a

pulumi import
